With her greatest hits album #1 to Infinity in stores today, Mariah Carey debuts a sneak peek of the Brett Ratner-directed video for “Infinity.” In the 37-second clip, Mimi shines in all her diva glory as she gets ready to hit the stage at her Las Vegas show at The Colosseum at Caesars Palace. She gets glammed up backstage, scrawls the infinity symbol in lipstick on her mirror, and rummages through her designer closet.

Last night, Mariah performed a medley of “Vision of Love” and “Infinity” at the Billboard Music Awards. Tune in to “Jimmy Kimmel Live” tonight for another performance.
